APPARATUS roa FORMING .mp rinsEm'me RECEPTACLE-CLOSURES.

Be it .:lmown"that I, CHARLES FnANois diiimmsya citizen ofthe UnitedStates, re-

' J into cylindrical paper cmilk -orlother liquid or solid goods.illustration, the apparatus chosen is such as siding at Washingtom-inthe District of Columbia, haveinvented [certain new and useful iImprovements I in Apparatus for Forming and InsertingReceptacle-Qlosures, ofwhich' the followingis a specification, referencebeing had therein to the accompanying drawing. 7

This invention relates to apparatus for insertingthem in reforming cuplike closing disks and inserting them in flexible receptacles for contaning or is adapted for cutting. disks from" paper stock-shaping ordrawmgthem-to the form of shallow cups and forcing them directly bottles(by the action of a plunger which first co-acts with an annular die indrawing them into proper shape) without releasing them or giving andinstantly releasin 40 than inusing metal.

them an opportunity to spring out of exact form given them .by theforming devices. it is essential that the the instant when insertionbegins. Usually bottle bodies are presented automatically in rapidsuccession, each resting for aninStant to receive its closure and thenmoving on togive place to the next. Itapidity of opera- 'tion ispractically indispensible in this particular art, and difliculty hasbeen found in adjusting the bottle body to exact form and exact positionduring its momentary rest,

it before it is moved onward. It is also to e noted that thedifliculties where paper is used are much greater Whatever the material,the difficulties are overcome in placing the bottle so near'the closureforming devices that the closure is-partly inserted before it iscompletely formed, and in pro-' viding simple bottle adjusting deviceswhich are compelled to act synchronously with the inserting lunger, sothat the bottle is necessarily 'he d prec sely'in form and positionduring the proper interval, and no longer, whatever the speed ofoperation.-

is-a side elevation, partly in section, of so much of the machine as isneeded to illus-,

trate the construction and action of the novel devices. Fig. 2 is asection on the line 2-2, Fig. '1. Fig. 3 is a section on the line Inthese views, A, A represent uprights provided with vertical ways for areciproeating cross-head B, C a support for an an--' nular cutting dieplate D and a smaller concentric forming die E.

Centrally pivoted at M in the supportC, upon opposite sides respectively,

of the bottle are adjustin jaws N, eachhaving its inner end adapte tofit one side or half of a cylindrical bottle of the size used. Thesejaws assume the position shown in dotted lines when the cutting plungeris in raised position, leaving the bottle free. to move bodily betweenthem. Through the outwardly projecting end portion N of each jaw ispassed a rod 0, and the end portions of each rod lie, respectively, inslots in the lower portions of bars 0', the upper ends of which arepivoted to the plate carried by the crosshead, as shownin slots Q. "Theparts are so proportioned that when the cutting plunger nears thelowerlimit of its movement, the rods 0, lying then in the upper ends of theslots, are suddenly forced downward swingin the jaws to the positionsshown in full lines. The bottle end is thus suddenly grasped, pressedinto true cylindrical form and accurately held in registry with theplunger J, which instantly descends forming the disk into a cup andinsertin' it in the bottle, the lower part. of the flange closure or cubein inserted before the upper portion 0 the ange leaves the formingdie. ,The lungers then rise, releasing the jaws which fall to initialposition, the falling being accelerated if desired bysprings P.

, Obviously the action of the jaws or adjusters would be the samewhether or not the inserted closures be cup-like, and it is also evidentthat they may be actuated difierently without departing from this partof my invention, so long as they are compelled to act synchronously withthe insertin device. It is also plain that it is optional whether thebottles be circular in cross section if the jaws or adjusters correspondin form with the selected cross section; and indeed the jaws permit theuse of certain noncylindrical forms not otherwise practically available.I

What I claim is: w

1. The combination with a reciprocating forming and inserting plunger,of an annular die adapted to co-act therewith in forming a closure, analining support for a pliable receptacle, normally disengaged receptacleforming jaws arranged to grasp the end'of such receptacle and press itinto shape and position near said ;'die, and automatic meansforactuating said jaws as the plunger makes its inserting advance.

2. The combination with a reciprocating closure inserting plunger, of anannular coacting formin die fixed in the path of the plunger, an a iningsupport for a flexible bottle, jaws arranged to be moved into and out ofposition for pressing the open end of such bottle into exact conformity:with the shape of the closure to be inserted therein by the plunger,and means whereby the insertin advance of the plunger. moves said jawsinto bottle-shaping position alongside said die, substantially assetforth.- 7

3. Inapparatus of the class described, the

combination withan annular forming die,

of a larger concentric cutting die above the same, a reciprocatingformin and inserting lunger arranged to co-act wlth the forming 1e, areciprocating sleeve-like cutting opposite sides thereof, and automaticmeans for compelling said jaws to seize and adjust theopen end of areceptacle upon said support an instant before insertion of the closureby the forming and inserting plunger. In testimony whereof I aflix mysignature in presence of two witnesses.
